Granuloma Formation
The body walls off the foreign material with hard, lumpy scar tissue (granuloma) that deforms the penis.
Key features
- Hard nodules form
- Irregular, lumpy shaft
- Progressive over time
- Excision required
Safe removal of dangerous self-injected substances — Vaseline, silicone, paraffin, or mineral oil — with granuloma excision and skin reconstruction. Board-certified urologist in Seomyeon, Busan from $1,000. Dr. Moon Hyeon-chang has extracted and reconstructed hundreds of cases over 15+ years.

Self-injection of Vaseline, silicone, paraffin, or mineral oil into the penis — sometimes done for enlargement — leads over time to hard lumps (granulomas), deformity, infection, skin breakdown, and pain. Learn from Dr. Moon Hyeon-chang why these substances must be removed and how extraction with reconstruction is performed. 15+ years of experience, explained in clear English.
Dr. Moon personally manages these complex cases at our Busan Seomyeon practice. Removal is rarely simple — the material infiltrates tissue and is usually combined with granuloma excision and skin reconstruction. Honest assessment of what can be restored is central to good care.


Injected Vaseline, silicone, and paraffin cannot be dissolved — they must be surgically excised together with the granulomatous tissue they form, followed by skin reconstruction.

Injected substances do not stay put or stay safe. These are the complications that make removal necessary.

Foreign material is a nidus for chronic infection, abscess, and discharging sinuses.
Injected substances migrate and clump, causing asymmetry, curvature, and an unnatural feel.
Pressure and inflammation can break down overlying skin, cause pain, and impair function.
Because injected material infiltrates tissue rather than forming a neat pocket, removal involves excising the affected tissue and reconstructing the skin envelope — often the more demanding part.
Examination and sometimes ultrasound map how far the material has spread and which tissue is involved.
Mapping guides how much tissue must be excised.
The injected substance and surrounding granulomatous tissue are surgically removed as completely as safely possible.
Complete excision reduces recurrence and infection.
Remaining skin is assessed — if too little healthy skin remains, reconstruction is planned.
Often the skin envelope is the limiting factor.
Skin grafts, local flaps, or scrotal flaps restore coverage where excision leaves a deficit.
See penile skin reconstruction and scrotal flap pages.
Extensive infiltration may need staged surgery — excision first, reconstruction once healed.
Staging improves results in severe cases.
Performed under general or regional anesthesia; extent of disease determines stay and recovery.
Larger cases may need a short inpatient stay.
These cases are highly individual. The substance, how long ago it was injected, and tissue damage determine whether removal is single-stage or staged with reconstruction.
What was injected, when, how much, and current symptoms — pain, lumps, infection, or deformity.
Mapping the extent of granuloma, skin involvement, and remaining healthy tissue.
Ultrasound to assess spread; bloods and swabs if infection is present, treated before surgery.
Single- vs staged plan defined, reconstruction method chosen, anesthesia and recovery discussed.
Approach depends on how much tissue is involved. Localized cases may be single-stage; widespread infiltration needs staged reconstruction.
Dr. Moon grades cases by extent of infiltration and skin damage to choose between simple excision and staged excision-plus-reconstruction.
Recovery focuses on infection control and protecting any reconstruction. These steps support the best outcome.
These cases often involve infection — finish the full prescribed course.
Limit activity in the first week, especially if a flap or graft was used.
Nicotine endangers reconstruction healing — stop before and after surgery.
Abstain for 4–6 weeks while tissue heals and any reconstruction settles.
Follow dressing instructions carefully, particularly between stages.

Foreign body extraction in Busan starts from $1,000 for localized, single-stage removal. Cases needing flap reconstruction or staging range $5,000–$12,000 depending on extent.
All prices include consultation, the procedure(s), and 6-month WhatsApp follow-up.
These substances do not stay in place or stay inert. Over months to years they form hard granulomas, migrate, cause infection and abscesses, and can break down the skin — leading to deformity, pain, and functional loss. Antibiotics cannot fix this; the material must be removed.
The goal is to remove as much as safely possible. Because injected substances infiltrate tissue rather than forming a neat pocket, complete removal can be difficult, and some excision of involved tissue is necessary. Dr. Moon gives an honest assessment of what is achievable in your case.
Often yes. Removing the material and granuloma frequently leaves a skin deficit that needs grafting or a flap (local or scrotal). Whether reconstruction is single-stage or staged depends on how much tissue is involved.
Most patients see major improvement in pain, infection, and deformity. Final appearance depends on how much damage occurred before removal — earlier treatment generally gives better results. Erectile bodies are usually unaffected as surgery is in the skin and subcutaneous layer.
Plan 10–14 days for single-stage cases including a follow-up before flying. Staged cases need longer or a return visit; Dr. Moon coordinates and monitors via WhatsApp between stages.
Removal often requires skin reconstruction. See grafts and flaps in detail.
